NewsInfections with parasites affect the local flight behaviour of swallows
Swallows infected with parasites move less and in smaller ranges than healthy ones – with detrimental effects on their foraging success and their survival.

NewsLyme borreliosis: New approach for developing targeted therapy
A research team has made significant progress in understanding the mechanism of Lyme borreliosis infection and identified a potential way forward for the development of targeted therapies that do not rely on antibiotics.

NewsMaternal antibodies interfere with malaria vaccine responses
Maternal antibodies passed across the placenta can interfere with the response to the malaria vaccine, which would explain its lower efficacy in infants under five months of age, according to research.

NewsPolar bears’ exposure to pathogens is increasing as their environment changes
As the Arctic warms, polar bears now face a greater risk of contracting several pathogens than bears three decades ago, a new study reveals.

NewsResearchers probe parasite transmission in turkey flocks
As scientists learn more about a deadly parasite’s ability to move from host to host in turkey flocks, a long-standing theory is in question and opens the door to new preventative measures. Source: U of A System Division of Agriculture photo Histomonosis is a deadly disease to turkeys. ...

NewsStudy identifies potential targets for treatment of visceral leishmaniasis
Discovery of a novel class of proteins that help regulate the parasite’s essential cellular functions could lead to the development of more effective drugs against the disease. More than 3,500 new cases are notified each year in Brazil.

NewsStudy reveals how parasites thrive by balancing specialisation with exploiting diverse species communities
A new study reveals that the prevalence of malaria-like blood parasites in birds increases with the number of species present in local bird communities. The findings indicate that parasites thrive when they can exploit a wide range of different bird species.

NewsScientists develop enzyme complex to find Achilles heel of protozoan parasite
In an effort to find a new weak spot of the protozoan parasite Trichomonas vaginalis, researchers have succeeded in preparing a key enzyme complex – the proteasome.

NewsRates of a tick-borne parasitic disease are on the rise
Cases of babesiosis increased 9% per year, on average, between 2015 and 2022 and nearly half were co-infected with another tick-borne illness such as Lyme disease, according to a new study.

NewsScientists design new drug to fight malaria
Scientists have designed a new drug against malaria and identified its mechanism of action. MED6-189 is effective against drug-sensitive and drug-resistant P. falciparum strains in vitro as well as in a humanized mouse model.

NewsScientist studying parasite-derived vesicles in babesia virulence and vaccine development
Fatah Kashanchi, Professor of Virology at George Mason University, has received funding for the study: ’Parasite-Derived Vesicles in Babesia virulence and Vaccine Development’.

NewsScientists unveil tactics of how viruses move through insects for transmission of diseases
Researchers have uncovered the clever tactics viruses use to spread through their insect hosts and potentially infect other animals. This knowledge is particularly crucial for combating viruses that spread from insects to humans or livestock.

NewsHijacking the command center of the cell: nuclear parasites in deep-sea mussels
Researchers have revealed how a bacterial parasite thrives inside the nuclei of deep-sea mussels, a remarkable feat given that the nucleus is the control center of the cell.

NewsNewly discovered viruses in parasitic nematodes could change our understanding of how they cause disease
New research shows that parasitic nematodes, responsible for infecting more than a billion people globally, carry viruses that may solve the puzzle of why some cause serious diseases.

NewsResistance found in parasite infecting cutaneous leishmaniasis patient
Researchers who analyzed samples from a 46-year-old patient in Brazil found an amphotericin B-resistant strain of the parasite Leishmania amazonensis circulating for the first time in the country.

NewsFirst-of-its-kind vaccine expands malaria protection for pregnant women
For the first time, immunization with a malaria vaccine has been shown to protect mothers from malaria during pregnancy and to protect for two transmission seasons without booster doses of vaccine.

NewsTrojan horse method gives malaria parasites a taste of their own medicine
Researchers have developed a trojan horse method that tricks malaria parasites into ingesting a fatal dose of drugs by exploiting the parasite’s need for cholesterol to survive.

NewsTicks’ secret allies: Bacteria’s hidden hand in tick survival
A new study of the relationship between the brown dog tick, Rhipicephalus sanguineus, and its Coxiella-like symbiotic bacteria reveals the bacteria help the ticks by providing essential B vitamins and possibly other nutrients like L-proline.
